  • The M-6200A Digital Voltage Regulator Control is a microprocessor-based step-voltage regulator load tapchanger control.

    The control is designed for initial OEM installation on new regulators or to replace a particular manufacturer’s regulator control. The panel is designed to mechanically and electrically replace an old control, with mounting hardware to facilitate the replacement.

    Interrogation of the control and setting changes are made via the user interface, or through the communications ports. User interface consists of a 20-character by 2-line backlit LCD display and six pushbuttons. Two passwords available to the user are accessed by the pushbuttons and a third is accessed through the communications ports. All setpoints are stored in nonvolatile memory which is unaffected by control voltage disturbances.
     
    Two operation counters are provided. One counter may be reset; the other may be preset by a user with appropriate security passwords.
     
    Eleven LEDs are used to indicate Tapchanger RAISE and LOWER command status, REV PWR, Reverse Power detection, CPU OK, ALARM, V/RED Voltage Reduction in Effect, MANUAL, LOCAL and TX/RX and Neutral Position indicator.
     
    The alphanumeric display and six pushbutton interface provides complete front panel access to the scrolling menu program. The control applies to regulators with ±16 taps.
